So I rinse out my carboys immediately after transferring beer to bottling bucket and make sure all the yeast and hips are gone then I'll fill with pbw and let sit then if there is krausen gunk on the side I'll take my brush and hopefully it all comes off. Then rinse real good and let the carboy dry in the sun. So I look today after its all dry and I can see on the side the scrape marks from the brush, I don't know if this is left over stuff the brush didn't get but is this an issue? The glass is clean there are no visible krausen or gunk on the side just like if you swiped your fingers across a dirty window. So I don't want an infection so is this a problem or will just star San it before a brew day will b fine. What would you do, another pbw or oxy soak and rinse or just leave it.
 
You may be seeing brush marks in cleaner residue. Both Oxy and Pbw need hot water to rinse them.

Prob right. Is this any prob going forward or will the star San clear it up when I soak it on brew day. I use hose water which obviously cools when I'm rinsing so it could just be residue. I just don't want to think I'm leaving something that will induce an infection. On brew day I'll fill it up with star San and let it soak for a good 30 min before dumping it and rinsing before I'll fill it with the wort and I cover the opening with sanitized foil.

Rinse it out with hot water (wear rubber gloves when handling glass and hot water). Starsan is cold and it's not going to rinse the residue away.
 
You will need to remove the residue left in the fermentor by the Oxy or it will be in your next beer. Oxy smells bad so I imagine it tastes even worse.

There is no need to fill the fermentor with cleaner or sanitizer. Begin the carboy cleaning by adding one gallon of tepid water, and shaking to remove loose residue. When you shake, hold the fermentor tight to your body and create agitation by movement of your upper body. Little chance of dropping the carboy this way.

After the loose debris is flushed out, add tepid water to the fermentor to just cover the krausen line, when the fermentor is inverted. Let it sit for a day, out of the sun. With the carboy held in a tilted position, brush the inside. Look for small dark specks of residual krausen. Rinse well with tepid water. I use PBW. Sometimes the krausen line has floated free in just a couple of hours with the PBW solution.

I store my carboys with Starsan solution in them. Add a cup of sanitizer, agitate to foam the inside, plug. Store inside.

I'll dump the sanitizer from the carboy the next brew day and add new sanitizer as a security measure.

Adding hot water to a cold glass carboy can begin stress fractures. Same as possible stress fractures adding cold water to a warm glass carboy.

Hope this will be of some help.
 
Hot water in glass carboy? Last time I even thought of that a disaster occurred.

I put 2 cups bleach in the carboy fill with cold water let sit for a day or two. All of the stuff falls off. Rinse for a few minutes with cold tap water air dry.
